Took my 850 brick to have it smog tested, when the technician, put it on the dyno. it over heated???? It has never done that before... he would not test it, so I filled up on antifreeze and drove home... everything worked fine. I replaced the fan relay and thermostat and every thing seamed ok... when I took it back to the test facility and the tech. put it on the dyno it over heated again????.. Every thing check out ok. Put in a radiator. The fan seams to run well. Could this be the problem???? Has anyone else had this problem???
FYI it has 157,000 miles.
